I don’t know what heat transfer oil is. Low temperature – there are low-temperature carbon steel materials, such as ASTM A333.

It is recommended that you use seamless steel pipes made of Q345E, produced in accordance with the standard GB/T 6479-2013 for seamless steel pipes used in high-pressure fertilizer equipment. Q345E seamless steel pipes produced according to this standard must undergo a Charpy test at -40°C (low-temperature impact test). It can meet your requirements. For your reference
